About FINE FILTER
A fine filter (often referred to as a secondary or polishing filter) is an advanced filtration stage designed to trap minute contaminants that slip past coarse strainers or pre-filters. It handles particles typically ranging from 1 to 10 microns (such as fine sediment, pollen, and bacteria) across air, gas, and liquid systems.
1. Primary Product Configurations
A. Liquid / Water Fine Filters
- PP Micron Ultra Filtration System: Houses melt-blown or pleated polypropylene depth cartridges. It handles high throughput and targets fine suspended solids down to 1 micron. [
- High-Efficiency Bag Filters: Employs fine felt or microfiber bags inside an SS housing. They offer high dirt-holding capacity and up to 99% efficiency for capturing fine pipeline rust and clay.
B. Air / HVAC Secondary Filters
- Flange & Box Type Panel Filters: Utilizes HDPE or synthetic non-woven fiber media pleated over an aluminium mesh. These are graded from M5 to F9 under EN 779 standards.
- Rigid V-Bank / Pocket Filters: Heavy-duty designs built with large surface areas. They sit immediately after air pre-filters to safeguard terminal HEPA/ULPA systems from premature clogging.
2. Sizing & Dimension Standards
- Standard Air Module Dimensions: Commonly framed in sizes like 610 mm x 610 mm (24" x 24") or 545 mm x 545 mm, with depths of 50 mm, 100 mm, or 300 mm.
- Liquid Housing Diameters: Single or multi-round cylinder shells spanning from 4 inches to 24+ inches depending on the flow grid.
- Connection Formats: Available with standard ANSI flanges, DIN flanges, or NPT threaded ports to match existing manifold structures.
3. Core Technical Specifications
- Micron Precision Profile: Available in nominal ratings (retains 85% of target particle sizes) or absolute ratings (retains 99.9% for sterile loops).
- Flow Capacity Scale: Liquid configurations range from 1,000 to 10,000+ Litres Per Hour (LPH), while air configurations support multi-stage industrial ventilation.
- Structural Frame Materials: Manufactured with durable SS 304, Galvanized Iron (GI), or Anodized Aluminium to resist corrosion.
4. Target Industry Applications
- RO Pre-Treatment: Prevents micro-particles from fouling expensive Reverse Osmosis membranes.
- HVAC & Cleanrooms: Serves as secondary filtration in hospitals, server rooms, and pharmaceutical facilities to trap pollen and mold.
- Pneumatic Protection: Cleans compressed air and technical gas lines upstream of high-accuracy flow meters and spray nozzles. [

- Are you looking for a fine filter for liquids (water/oil) or for air/gas ventilation?
- What is your exact target micron rating (e.g., 1 micron, 5 microns)?
- What is your system's operating flow rate or volume capacity?
